PAPER-MAKING MACHINE.

Specification of Letters Patent.

Patented Nov. 23, 1909.

Application filed March 9, 1908. Serial No. 419,846.

To all whom it may concern:

15e it known that I, Josnrlr H. WALLACE, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, United States of America, have invented certain new and useful Improvements in Paper- Making Machines, of which the following is a specification.

My invention relates to improvements in paper making machines and its object is to improve upon apparatus of this character and to increase its ehciency, adaptability and ease of operation.

It relates, especially, to the Fourdrinier mechanism and its associated parts and consists in the construction and arrangement of parts which I will describe in the following specification and the novel features whereof I will point out in claims.

Referring to the drawings, Figures 1 and 2 are a side elevation of certain parts of a paper making machine and associated parts showing my invention applied thereto. Fig. 3 is a plan view of one end of the apparatus shown in Fig. 1 with certain parts removed to more clearly show the construction. Fig. 4 is a sectional end elevation of an adjusting mechanism which I employ in carrying out my invention. Fig. 5 is a top plan view of a detail of the apparatus, this figure showing a portion of a speed regulating mechanism.

Like characters of reference designate corres onding parts in all of the figures.

10 esignates the foundation upon which various parts of a paper makin machine are mounted. 11 are I-beams forming a part of this foundation and supporting the Fourdrinier portion of the machine.

l2 designates a frame of structural steeel or other suitable construction which forms the base of the Fourdrinier mechanism. 13

is a hinge-block at the rear end of thisV frame 12 connected with the foundation 10.

14, 14 are a pair of pedestals suitably affixed to the foundation 10 and connected together by a tie-bar 15 and arran ed lto guide the forward end of the Four rinier mechanism.

16, 16 are guide-blocks secured to the end of the frame 12 and rejecting into the pedestals 14. These Igu1de-blocks and pedlestals are so arranged that the blocks may move up and down within the pedestal but are firmly held against lateral movement.

2() is a supporting block upon the foundation 10 which is arranged to hold the for ward end of the F onrdrinier mechanism through an adjustable supporting arrangement which I will describe fully hereinafter.

All the parts of the F ourdrinier mechanism, including the shower pipes 32, the suc (ion boxes 33 and the flow-box 31, are mounted upon the frame 12. The showers are connected with a pipe 34 which is connected with another pipe 35 from a suitable source of water supply through a fiexible conductor 35A. The suction boxes are connected with a header 36 in the usual manner and with a pipe 38 from a vacuum pump through a flexible conductor 38A.

39 designates the F ourdrinier wire which is carried in the usual manner from the breast-roll 30, the lower roll 24 of the couch 23 and over or under intermediate carrying rolls and guide rolls.

40 is an engine for driving a paper making machine. In the drawings I have shown a steam engine, the fly-wheel 41 of which is connected by means of a belt 42 with a countershaft-pulley 43. 44 is another belt extending to one or more other countershafts and through other mechanical connections to the various driven members of the apparatus.

45 is a centrifugal governor for controlling the speed of the engine. This governor is connected with the driven shaft of the engine by means of belts 4G, 47 and intermediate controlling mechanism 50 which is clearly shown 1n Fig. 5.

The controllin mechanism 50 comprises a cone-pulley 51 riven by the belt 46 and a similar cone-pulley 52 which is connected with the governor 45 by the belt. 47. These two coneulleys are connected by a friction wheel 53 oosely mounted upon a collar on a threaded shaft 54. The position of this friction wheel upon this shaft may be adjusted by rotating the shaft which may be done b rotatin the vertical regulating shaft 55. pair o bevel-gears 56 connects the vertical regulating shaft and the threaded shaft 54. 57 is another pair of bevelears which connects the verticl shaft 55 wlth a handwheel 58. One of these bevel-gears and the hand-wheel are connected together and are mounted upon a sleeve 59 which is loosely supported upon a shaft (l0. As the length of the vertical Ishaft 55 is variable, a. splined sleeve. 55A may be interposed to provide for this change in length. (il designates another handavheel and this is keyed or otherwise atlixed to the shaft (itt. A pair ot worms` (L, h2 are also attached to the shaft (i0, and these are in mesh with the wormgears GB, till upon vertical screw-stuitts (il, U4. These serew-shatts pass through blocks E21 which are threaded to tit the thread on the shafts and are provided with gudgeons which rest in the supporting bloehs Qt). Shoulders (55 near the upper end ol each of these shafts support roller bearings ti'ti. and swivel-blocks (S7 resting upon these bearings and engaging with portions 1T of the frame 12, sustain the weight. of the traine and the parts of the apparatus which are supported upon it.

68 is a clutch member splined to the shaft 50 and arranged to be moved into engagement with the sleeve 5t) which is properly formed for this purpose. A hand-lever (39, connected with the clutchmeinber (3S, is pro-- vided for this purpose.

By means of the mechanism above described, the speed of the engine 40, which is controlled by the speed governor 4:5, may be varied by manipulating the liand\vl1eel 58. The hand-wheel G1 is for the purpose of ad justing the osition of the frame 12 and the entire Four rinier mechanism which it supports. It has already been shown that the rear end of this frame is supported by the hinge-block 13 and its forward end by the screwshafts G4. As the latter are rotated they move up or down in the blocks Q1, and with these screws the forward end of the frame 12 is elevated or depressed. By this arrangement the forward end of the entire Fourdrinier mechanism may be raised to any desired height to give a decided downward slope to the upper surface of the Fourdrinier wire, or it may be depressed until this end of the frame is lower than the rear end as is indicated by the dotted lines at 12A in Fig. 1.

The two adjustments of speed and slo e above described may be made independent y of each o-ther. By throwing in the. clutchmeinber G8 both of these adjustments may be made simultaneously, and the mechanism is so arranged that the speed of the engine, and consequently of the entire machine which it drives, will be increased when the forward end of the frame 12 is raised.

Slight adjustments of the slope of the Fourdrinier wire have been made for the urpose of varying the quality of the manu- Ifnactured paper. It has also been found advantageous to so construct the wet end of a aper making machlne to give the Fourrmier wire a substantial downward dechnation in order to allow the gravity [low of the stock upon the lt`ourdrinier wire to increase the output of the machine by increas ing the speed at which the stock is fed tn the various presses and other parts ol the apparatus. ln carrying out the latter idea machines have been installed with the forward end ol' the lfourdrinier wire blocked up, which arrangement. has` necessitated the readjustnu-.nt of the various parts olI the mechanism which are` associated with the ltourdrinier wire. A paper making machine thus` set up and adjusted has great ellieiency tor manufacturing a given kind and quality of paper.

(.)ne oi' the objects of my invention is to provide a niaehine which is capable of using different varieties of stoel( and whiclr may be used for making papers ol. different classes and qualities. The apparatus which l have shown and` described may be readily and almost immediately changed to suit varying conditions. To accomplish this re* sult I have mounted the entire Fourdrinicr mechanism. including the flow-box, upon an adjustable base and have associated with it an arrangement for controlling the speed of the driving engine. lt is a point of iinportance that the lowbox should be mounted upon this movable frame as thereby the head which causes the flow of stock onto the Fourdrinier wire is maintained constant regardless of the vertical position of the forward end of the frame. It is also important that all of the parts associated with the Fourdrinier wire be mounted together on the same frame as b v this arrangement the various parts remain in the same relative positions regardless of the amount of slope which is given to the Fourdrinier wire.

In making some classes of paper it is desirable to have the stock carried upgrade by the Fourdrinier wire in order to gain the desired results, and in some cases a consider4 able down-grade in the Fourdrinier wire may be used advantageously. My improved apparatus may be used for a large variety of work, and by the arrangements which I have described, the machine may be quickly changed from one class of paper to another. It is also possible to give the slight variations of slope in the Fourdrinier wire which are necessary for obtaining the proper re sults.in the quality of the kind of paper which is being made at a given time. u

An important; feature of this inventlon is that the desired adjustments of slope and speed may be used while the machine is runnin and therefore without interrupting its pro uction. As a result it is possible to change a machine from conditions for mak ing one class of paper to those requlred tor another class of paper without the necesslt f of shutting down the machine. It is wel known that such a change has heretofore required a shut down of the machine and entailed a considerable loss of time and a large proportion of a days product of the machine.

The particular mechanism for regulating the speed of the engine and for adjusting the slope of the apparatus are arbitrarily selected and of course various other n'iechanisms may be used if desired to accomplish these results. It is well-known that the engine is connected through suitable arrangements with the various units of the paper making machine so that when its speed is changed, the speed of the various units is also changed. It is also well-known that between the driv ing engine and each separate unit, independent speed varying mechanisms are employed, but as these form no part of the present invention, I have not thought it necessary' to illustrate them in the drawings.
